Subject: [PATCH 1/3] arm: Use internal symbol for _dl_argv on _dl_start_user
Date: Mon, 1 Nov 2021 09:50:01 -0300 [thread overview]
Message-ID: <20211101125003.500945-2-adhemerval.zanella@linaro.org> (raw)
In-Reply-To: <20211101125003.500945-1-adhemerval.zanella@linaro.org>
The lld does not support R_ARM_GOTOFF32 to preemptible symbol (_dl_argv
has global visibility). Use the internal alias instead (one option
would to use HIDDEN_JUMPTARGET, bu the macro is not defined for
!__ASSEMBLER__ and I made this patch arm-specific to avoid require to
check extensivelly on other architecture it this might break something).
Checked on arm-linux-gnueabihf.
